When doing format changes I'd recommend taking a look at Chapter 7 of
http://shop.oreilly.com/product/0636920023913.do which has a hint how
stuff might be stored in AD. Also, when talking to Metze I learn that
there are some optimizations possible in the way we store attributes.

The problem with format changes is that any time we do that we have to
be backwards compatible and have upgrade code. Just take a look at
pdb_tdb.c. We should be careful to not accumulate too much of those
versions, so some good consideration is due here I guess.
